Some friends like to put one leg on the other when they are bored at work, which is commonly known as "crossing the legs". Legend has it that the sitting posture of Erlang God is like this, hence the name "crossing the legs". In life, some friends are unable to pose like this, why is this?
To understand this issue, one should first understand the anatomical principles involved in crossing the legs. To complete this action, the adductor muscle group of the thigh needs to be mobilized. This muscle group is controlled by the obturator nerve emanating from the lumbar plexus. If the obturator nerve is damaged due to certain reasons (such as trauma, surgical side injuries, etc.), it will result in the affected leg not being able to be placed on the healthy side of the leg, which leads to the phenomenon of not crossing the legs.
In addition, some friends are unable to cross their legs due to gluteal muscle contracture. This condition is mainly caused by repeated intramuscular injections into the buttocks, characterized by an external "eight" gait, inability to squat with knees in a frog like position, limited running and jumping, positive circled sign and cross leg test. Fortunately, the disease can generally be cured by surgical methods.
In addition to the pathological factors mentioned above, normal physiological factors such as leg weight and length can also lead to the inability to cross legs.
However, crossing your legs is not a good habit, as it can pose many health risks:
For men, the local temperature rise caused by crossing their legs may affect reproductive health and may also have adverse effects on the prostate, leading to prostatitis.
Cross legged crossing increases the pressure on the internal structure of the knee joint, leading to nutritional disorders and increased wear and tear of the cartilage. For elderly people with varying degrees of cartilage structure degradation, it increases the risk of osteoarthritis.
3. When crossing the legs, due to uneven force on the upper leg and inward deviation, it may cause an increase in pressure in the medial knee joint space and worsen cartilage wear. At the same time, the "fibular collateral ligament" located on the outer side of the knee joint is continuously pulled, causing it to relax, possibly forming a knee joint subluxation on the basis of existing osteoarthritis, which gives the appearance of an O-shaped leg.
4. For those patients with diabetes and various lower limb vascular diseases, due to the poor nutrition supply of the peripheral nerve itself, they have peripheral neuropathy, and the effect of crossing their legs is much greater than that of health. Please stop crossing your legs.
Cross legged crossing can increase the risk of many diseases. It is recommended to reduce the frequency of cross legged crossing. For some patients with related basic diseases, it is necessary to correct this poor sitting posture.
